Built-in electric field-triggered electron transfer for selective singlet oxygen generation with intrinsic chemiluminescence

Abstract

Here, a built-in electric field (BIEF)-driven strategy has been proposed for the selective generation of singlet oxygen (¹O₂) mediated by electron transfer in a Eu-CuO@PNDs heterojunction, featuring intrinsic chemiluminescence (CL). Taking electron-rich active pharmaceuticals (scopoletin) as an example, the potential application of this ¹O₂-dependent CL system was evaluated. This work provides a novel strategy for ¹O₂ generation and CL amplification via BIEF-mediated electron transfer.
